SQO100-48-1.5, SQO100-48-1.5N
48Vin
1.5Vout
25A
Description
The SQ(Enclosure)/SQO(Open Frame) family of high power
density, high efficiency DC/DC converters deliver up to 25A
in an industry standard quarter brick footprint. They are
targeted specifically at the telecommunication, industrial
electronics, mobile telecommunication and distributed power
markets. With a wide input voltage range of 36-75V they are
available with output voltages of either 1.5, 1.8, 2.5, 3.3 or 5
Volts. All models feature an input filter, input undervoltage
lockout, output overvoltage and overtemperature protection,
output current limiting and short circuit protection. These
converters are available either in a package that is fully
enclosed with a six-sided metal shield or an alternative,
open-frame construction. In both cases the aluminum heat
spreader design achieves very efficient heat transfer with no
hot spots. The use of patented Flat Transformer technology
and other patented design concepts facilitate very low
temperature rise. The use of highly derated power devices
help to achieve high reliability, high performance and offer a
low cost solution to sys tems designers requiring maximum
power in small footprints.
